gcache.page.some_number full disk problems

07-15-2014, 12:01 AM

Hello,

We have a 3 node cluster setup, and it happens that nodes create a lot of gcache.page files and it leads to fulling disks on nodes and to node crash. Then node needs to be reinitialised and gcache.page.some_number files needs to be deleted. All those gcache.page files can full up the disks up to 90 GB, althought when node starts mysql data directory takes only 12 GB. It is Percona XtraDB Cluster 5.6. How can I limit the number of these files?
